Suppose that in a given kinetic experiment, the blue color appears in 14.5 seconds when the initial concentrations are
[Na, S2O3]. = 8.79 X 10M,
[C]. = 4.58 x 10M,
[H2O21. = 5.10 10M.
What is the rate of change of [ls") in reaction 1?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
